| 19:47.44 | prpplague | T0mW: hey, you remember your old project with tuxscreen + ide? |
| 19:47.50 | T0mW | yeah |
| 19:48.18 | prpplague | T0mW: i got a hack job i need to look at, do you still have some docs on your hack? |
| 19:48.45 | prpplague | T0mW: did you write a custom ide driver? |
| 19:48.48 | T0mW | Hmm, let me check, do you need source? 'cause I think that was a 2.4 kernel. |
| 19:49.02 | prpplague | anything you got would be helpful |
| 19:49.26 | T0mW | prpplague: no, modified the IDE driver where it went for the IO ports, I substituted my own memory regions. |
| 19:50.10 | T0mW | IIRC, whenever it did an INW or OUTW, I went through my memory mapped I/O |
| 19:50.30 | T0mW | looks |
| 19:55.52 | T0mW | prpplague: about what year was it that we were messing with that stuff? The source is not on the system, it is on cdrom now. |
| 19:56.13 | prpplague | T0mW: iirc around 2000 |
| 20:01.53 | prpplague | T0mW: do you remeber what kind of throughput you were getting? |
| 20:02.28 | prpplague | T0mW: basically i was looking at an 8-bit nand interface to 16-bit ide |
| 20:02.51 | prpplague | T0mW: do address-data-data |
| 20:05.40 | T0mW | prpplague: found it |

| 20:07.48 | CosmicPenguin | I need some kconfig fu - anybody volunteer to help? |
| 20:08.15 | prpplague | CosmicPenguin: i'll give it a go! |
| 20:08.51 | CosmicPenguin | I have a choice dialog |
| 20:09.05 | CosmicPenguin | And i want to set the default for said dialog based on other config settings |
| 20:09.21 | CosmicPenguin | so I want it to default to 16 for some and 32 for the others |
| 20:09.29 | CosmicPenguin | but I don't want to remove the option to change it, I just want to make the default stick |
| 20:10.04 | prpplague | one sec, let me get you an example |
| 20:11.29 | prpplague | CosmicPenguin: can you pastebin the kconfig option? |
| 20:12.22 | CosmicPenguin | Not easily |
| 20:12.57 | prpplague | CosmicPenguin: basically you just add something like: default 64 if CPU_S3C2410 |
| 20:13.01 | prpplague | CosmicPenguin: then repeat |
| 20:13.10 | prpplague | CosmicPenguin: basically you just add something like: default 128 if CPU_S3C2440 |
| 20:14.30 | CosmicPenguin | oh, sweet |

| 20:23.52 | *** join/#edev SpeedEvil (~user@tor/regular/SpeedEvil) |
| 20:26.10 | T0mW | prpplague: well, there was a bit of a performance hit due to the banging away between shorts and bytes. The Shannon "port" that I used was 8bit and the data register of the IDE is 16bit... |
| 20:26.58 | prpplague | T0mW: right |
| 20:27.12 | prpplague | T0mW: i'm in the same boat |
| 20:27.16 | T0mW | prpplague: talking with the other registers was direct, iirc. |
| 20:27.31 | T0mW | I had the address lines then. |
| 20:27.34 | prpplague | T0mW: but the nand flash controller can run alot faster |
| 20:28.35 | T0mW | prpplague: interesting thing is that the work on the shannon has spilled over into what I'm doing here on this project: using the IDE port to access one 16bit input and three 16bit output latches. |
| 20:28.48 | prpplague | T0mW: hehe |
| 20:29.05 | T0mW | prpplague: sort of like using the parallel printer port for system io, only betterer |
| 20:29.26 | prpplague | T0mW: most nand controllers have a nice 16bit read command that does double reads of the 8-bit port automagically |
| 20:30.06 | T0mW | prpplague: works great if you keep to 0x1{f,7}0..0x1{f,7}7 and stay away from the 0x3{f,7}6 port. |
| 20:30.12 | prpplague | hehe |
| 20:30.20 | T0mW | Heh |
| 20:30.24 | T0mW | :D |
| 20:30.26 | prpplague | CosmicPenguin: that config work out for you? |
| 20:31.07 | T0mW | prpplague: so, I've got this 80pin IDE cable hanging out of the computer and is plugged into the target system... |
| 20:31.43 | T0mW | prpplague: what do you need that old crap of mine for? |
| 20:32.29 | prpplague | T0mW: hehe for new crap |
| 20:32.57 | prpplague | T0mW: got a platform with a 8-bit nand flash controller available, but i want to be able to add a sata hard drive for larger storage |
| 20:32.59 | T0mW | prpplague: I'm positive that shannon is still here, in a box someplace. |
| 20:33.44 | T0mW | that sucking sound you hear is the target's performance taking a nosedive. |
| 20:35.03 | T0mW | prpplague: oh, I finally converted that assembly source over to C, I got it running (booting) Wednesday morning. |
| 20:35.16 | T0mW | lot of freaking work |
| 20:35.32 | prpplague | T0mW: i don't think the performance of the overall system will take a large hit |
| 20:35.40 | T0mW | oh |
| 20:35.43 | prpplague | T0mW: doing 8-bit nand flash is pretty high speed |
| 20:37.35 | T0mW | prpplague: http://www.openhardware.net/screenshot3000.gif |

| 20:39.23 | T0mW | prpplague: customized the insight to show the virtual registers (right center edge) |
| 20:40.00 | prpplague | nice |
| 20:40.05 | T0mW | it will probably run slower than molasses on a cold day, but it runs. heh |
| 20:40.41 | T0mW | who cares anyway, MIPS are cheap |
| 20:40.45 | prpplague | T0mW: i'm really interested in seeing how this nand flash to ide might work |
| 20:41.07 | T0mW | is that an IDE interface to the nand? CF card? |
| 20:42.03 | T0mW | prpplague: I assume that is what you are referring to, CF. |
| 20:42.30 | prpplague | T0mW: no, the other way around |
| 20:42.38 | prpplague | T0mW: the SoC has a nand interface |
| 20:42.58 | prpplague | T0mW: i want to go from the nand interface to a ide hd |
| 20:46.43 | T0mW | prpplague: well, I think that the IDE subsystem has changed dramatically in 2.6, they now have a PATA thingy which replaced what I was using with the 2.4 kernel. |
| 20:47.15 | prpplague | T0mW: yea |
| 20:47.25 | prpplague | T0mW: the platform structure would be pretty easy to change |
| 20:48.36 | T0mW | hmmm, turkeys are feeding in the woodlot next to me. Think I'll get that wrist rocket from ebay |
